UNITED STATES ,EDGAR M. BUTLER, 0F BROOKLYN, NEW YORK MOTOR-CAR-LIFTINGDEVICE. 1

Application filed March 22, 1922. Serial No. 545,716.

To all whom it may concern:

Be it known that I, EDGAR M. BUTLER,

a citizen of the United States, residing at New York city, borough ofBrooklyn, in the county of Kings and State of New York,

have invented a certain new and useful Motor-C'ar-Lifting Device, ofwhich the following is a specification.

This invention is a motor car lifting device for use more particularlyin garages, though also applicable for employment when it is desired tolift the forward portion of the car for the purpose of towing the same.

It frequently becomes necessary to elevate the front of a car to permitmore ready access to the underside of the car or to take the weight offofthe front wheels if it is de sired to tow the car after an accident tothe front wheels and for other reasons familiar to those skilledin theart.

It has been thfe'practice ,to accomplish this result by hookingchainsover the goose necks of the chassis frameor over the frontsprings, but as many of the latest style cars are provided with splashguards extending across the front of the chassis between the goosenecks, lifting of the oarby the use of suchchains invariably damages orbends the splash guards, causes the, enamel to be chippedtherefrom, anddistorts the guards, sohthat the lifting ofthe carby the use of chainsas heretofore practiced is not feasible. For the want of better means toaccomplish the enddesired, many mechanics prefer to firstrelease'theguards from the goose necks before attaching the liftingchains, but this not only occasions considerable loss of time, butrequires that the guards be'slightly bent out of shape before the chainscan thereafter be secured to the goosenecks or springs.

With the foregoing considerations in mind, the object of the presentinvention, is totprovide a convenient [and highly efficientliftingdevice which may be easily and eX- peditiously associated withthe forward partof the car to enable theli'fting thereof with out damageto the splash guard or necessitating the releasing or removal thereof.

The lifting device of the present inventiod'may partake of differentforms, but in its "preferred practical embodiment is in the formofarigid yoke of sufficient length 'toiextend across the front springs" ina transverse direction, Theopposite ends of the yoke'fcarry adjustablespring hooks which may be brought into engagement with the springs fromthe underside thereof and secured in position so that they cannotinadvertently become detached or slipped off. The yoke is preferablyprovided intermediate its ends with a hoisting ring adapted to beengaged by the hook of suitable hoisting tackle,by means of which thecar may be lifted. The advantage of this construction is that the carmay be safely hoisted and when in lifted position will besecurelymaintained against inadvertent falling, so that workmen may safely workbeneath the car or the car may be towed without fear of breaking looseand becoming further damaged.

Features of the invention, other than those specified, will be apparentfrom the hereinafter' detailed description and claims, when read inconjunctionwith the accompanying drawings. i

The accompanying drawings illustrate different practical embodiments ofthe invention. but the constructions-therein shown are to be understoodas illustrative, only, and not as defining the limits of the invention.v

Figure 1 is a front view of a car showing thehoisting device of thepresentinvention associated therewith.

Figure 2 is a front view of the hoisting device detached from the car,but showing" the springs of the car with which the hoisting devicecooperates in section,

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is a plan view of one end of the hoisting device shown inFigure 2.

Figure 5 is a frontelevation of a modified form of hoisting deviceembodying this invention.

Figures 6 and 7 are sections on the lines 6--6, 77, respectively, ofFigure 5; and,

Figure 8 is a fragmentary perspective of one end of the hoisting deviceshown in Figure 5. t

Referring to the drawings and more particularly to Figures 1, 2, 3 and4, 1 designates goose necks of a motor vehicle chassis frame, beneathwhich are disposed the two front springs 2. The splash guard 3' extendsbetween the goose necks and below the radiator 4 and is of differentshapes in the different makes of cars. The structure described is thatof a conventional car and is substan .to one another.

tially the same in all cars employing splash guards. f r a The liftingdevice of the, present invention as shown in Figures 1-- l is in theform of a rigid metallic yoke 5 preferably bowed upwardly intermediateits ends and provided at its center with a lifting ring 6, with whichthe hook of suitable hoisting tackle 7' is adapted to be engaged. Theyoke as shown best in Figure 3 is of substantially channel cross sectionand adjacent its opposite ends is longitudinally slotted as shown at 8in Figures :5 and 4, and through these slots 8 extend threaded shanks 9of rigid spring hooks 10. The spring hooks 10 may be con veniently madein the form of castings and are positioned for adjustment longitudinallyof the yoke on the upper edge thereof. Flanges ll extend along onemargin of the upper edge and engage with one side of each of the springhooks, so as to preclude rotary movement of said hooks on their threadedshanks 9. By virtue of this arrangement, the spring hooks may beadjusted longitudinally of the yoke to vary the span between them andmay be locked in anydesired position by means of wing nuts'12,

which thread on to the lower ends of the th-readedshanks 9 and engagewith'the lower edge of the yoke.

In applying the lifting device described to a car, the wing nuts 12 arefirst loosened and the spring hooks drawn apart, whereupon the yoke isbrought into a position to underlie the front springs 2 and to engagewith the under surface of said springs. The spring hooks are thenmanually shifted toward one another, so as to hook over the out sideedges of the springs 2 after the manner illustrated in Figure2,whereupon the wing nuts 12 are tightened to firmly secure the yoke tothe springs. The hoisting tackle 7 may thereafter be operated for thepurpose of lifting the car without fear of the yoke becoming releasedfrom the car and permitting the car to fall. I

- It will be apparent that in the construction shown. the yokewill restfirmly on the under side of the springs and will be free from engagementwith the splash guard 3, so that damage to the splash guard duringlifting in themannerdescribed cannot occur. The yoke asshown in Figures1' and 2 is bowed upwardly intermediate its ends and while this is thepreferred construction,

it is not necessarily the exclusive one, since theyoke might be madestraight or of other shapes if preferred.

In Figures 5e55, I have illustrated a modified form of the presentinvention wherein the yoke 5 is made straight and is composed of. twosections 14 and 15. These sections are of channel cross section asclearly shown in Figure 6 and are in telescopingrelation The springhooks '10 ,are

formed rigid and integral with the respective sections 14 and 15, asshown in detail in Figure 8, and the adjustment between these hooks isaccomplished through adjusting the screws 1% and 15 telescopically.These sec-' tions may be locked in adjusted position by a carriage bolt9 and an associated wing nut 12 The carriage bolt is passed through asquared opening in the section 15 and extends through a slot 8" in thesection 14. The slot permits of adjustment'of the sections, but they maybe locked in any posi tion by simply screwing down the wing nut. Thehoisting tackle is adapted to be secured to hoisting ring 6, which isconnected'by chains 16 to rings or shackles 17, which pass through,apertures in the flanges of the respective "sections 1% and 15, afterthe manner clearly shown in Figure 7, so that the lifting strain isproperly distributed throughout thetwo sections of the yoke.

The manner of applying the construction of Figure 5, willbe apparentfrom the fore going detailed description thereof, since it will appearthat the wing nut 12 will be loosened to permit the spring, hooks 10 tobe engaged with the springs of the vehicle and thereafter this nut againtightened prior to the lifting of the vehicle. v The foregoingdescription sets forth in detail two specific constructions embodyingthe present invention. I am aware, however, that the invention, iscapahle of m0difica= tion without departing from the spirit and scope ofthe invention which is to be under.- stood as broadly novel asire-commensurate with the appended-claims.

' I have hereinbefore referred more par.- ticularly to the use of thedevice of this] in- ,vention for lifting the forward part of a car, yetit will be understood that it may be employed to lift the rear portionof l car. 7 a a Having-thus fully described the inven. tion, what I.claim as new and desireto sec-ureby Letters Patent is;

1., A. lifting device for motor. vehicles embodying a rigid yoke withwhich hoisttackle is adapted to be associated, gripping membersassociated with the. opposite endslof the yoke and adapted to engage andgrip parts of'the car to-be lifted, and means for rigidly securing saidgripping members to the yoke to preclude inadvertentshifting of saidmembers. i i r 2. .A lifting device for motor vehicles embodying a rigidyoke'with which, hoisting tackle is adapted to be associated, springengaging hooks associated with; the opposite ends of the yoke, andmeansfor rigidly maintainingthe spring engaging hooks in spaced relationafter they have been. brought into engagement with the springs of thecar to be lifted to preclude inadvertent. disengagement. of the hooksfrom the springs.
